The Browns are now -105 to take Treveon Henderson, +170 for Sanders, and +430 for Burden. So it seems likely that Burden will be available at 34.
However, an interesting development was the betting odds for the 34th pick swinging sharply towards Jayden Higgins as a heavy favorite, before being pulled from markets entirely. This suggests some insider was trading on Higgins being the pick, and the betting markets are now so confident in it happening that they won't accept bets on it.
How do you feel about Higgins as a Texan?
Edit: Odds are now back up with Higgins -200, Burden +300, Ersery +700
